XII, D. 3 Crawford: Philippine and Asiatic Psyllidse 169 



easily visible from above. Genal cones large and broad, not 

 divergent, rounded at apex, continuing in same plane with vertex, 

 but separated therefrom by a deep furrow, about as long as 

 breadth at base, with short stiff pubescence. Antennae about 

 as long as body without wings, very slender. 



Thorax broad and robust, hairy. Legs short and stout; 

 hind tibiae with spur at base. Forewings broad, scarcely twice 

 as long as broad, membrane scarcely hyaline, apex broadly 

 rounded or a little angulate, veins setose; a darker band, often 

 with black spots scattered through it, extends from first cubital 

 vein around apex of wing to base of pterostigma ; central portion 

 light brown; second marginal cell differing in shape among in- 

 dividuals of the species. 



Abdomen relatively short and thick. Male genital segment 

 moderately large; forceps large, broad, spatulate, very broad at 

 apex, apical margin rounded, broadly and finely toothed; anal 

 valve longer than forceps, tapering to a small end. Female 

 genital segment not as long as rest of abdomen, much smaller, 

 tapering to acute end, dorsal valve a little longer than ventral. 



Mindanao, Butuan {Baker), 1 male; Davao {Baker), 1 male: 

 Luzon, Tayabas, Malinao {Baker), 1 female. A fourth speci- 

 men, a female, from Mount Banahao, Laguna, Luzon {Baker), 

 shows the venational characteristics of the Butuan male, but is 

 destitute of the wing coloration present in all the other specimens. 

 Whether this is a constant variation — a subspecies — or a chance 

 individual not wholly developed is impossible to judge from the 

 one specimen at hand. It appears that in this species there is 

 a considerable variation in wing color and body color and in 

 minor venational characters. 



Arytaina tuberculata sp. nov. Plate I, fig. 8. 



Length of body, 3.8 millimeters ; length of forewing, 3.5 ; width, 

 1.8; width of head, 1.0. General color orange to tawny brown; 

 eyes black ; abdomen dark brown ; antenna dark over apical half ; 

 wings brownish. Body large, robust, surface covered with short, 

 stiff pubescence. 



Head nearly as broad as thorax, large, strongly deflexed. 

 Vertex large, about half as long as breadth between eyes, each 

 half roughly triangular in shape with the two discal depressions 

 meeting at midline and forming one larger cavity, with a pro- 

 minent wartlike tubercle on each side between posterior ocellus 

 and antennal base; posterior ocelli elevated; anterior ocellus 

 in notched front margin of vertex. Genal cones large, as long
